Armorcast Gawk Screens on Single Slope Concrete Barrier (deter pedestrians)

Report Number(s): 0-7082

Description: Crash Test No. 440822-01-1 The installation consisted of a 100-ft long section of a cast-in-place single-slope concrete median barrier, with 20 sections of Armorcast® gawk screen panels mounted on top starting 23 inches from the upstream end of the concrete. The single-slope barrier was 42 inches tall, 24 inches wide at its base, and sloped symmetrically upward on both sides for a final width of 8 inches at the top of the barrier. The gawk screen panels were 63 inches long with a 6-inch overlap; thus, each individual panel spanned 57 inches. The panels were 24 inches tall and had a 6-inch wide, 1-inch tall base that sloped up on both sides for a final width of 2 inches at the top of the screen. The screens had two 9 ⁄16-inch slots spaced vertically on one end and two 9 ⁄16-inch holes spaced vertically on the opposite end in order to bolt the screens end to end on top of the single-slope barrier. Each screen was fixed to the barrier by being placed over a 26-inch tall post that was anchored to the top of the concrete barrier. The posts were centered on their respective screens, and a hitch pin attached to a chain welded to the inside of the post was inserted into a ¼- inch through hole in order to keep the screens from being easily removed from the posts.
